#The points that are higher or lower than the whiskers of the boxplot are called outliers. Since none of the variables have points that are higher or lower than the whiskers of the boxplot, outlier treatment is not necessary in this instance.
#There are many ways to deal with outliers or extreme values, but the one we'll use here is whinsorization, in which the points above the whiskers are replaced with the maximum value of the boxplot and the points below the whiskers with the minimum value.The outlier treatment will be carried out in this manner.
